In this paper, we deal with a sensor placement optimization problem for multi-point pedestrian flow monitoring systems, and provide an efficient algorithm. Our goal is to build a realistic and accurate model of the monitoring systems' pedestrian flow estimation performance in terms of their estimation errors. Also our model can represent sensor placement considering the number, types, locations and...
We propose an opportunistic ad hoc localization algorithm called Urban Pedestrians Localization (UPL), for estimating locations of mobile nodes in urban districts. The design principles of UPL are twofold. First, we assume that location landmarks are deployed sparsely due to deployment-cost constraints. Thus, most mobile nodes cannot expect to meet these location landmarks frequently. Each mobile...
